The Maine Mineral Value and Municipal Property Tax Reimbursement Referendum, also known as Constitutional Amendment 8, was on the November 8, 1983 ballot in Maine as a legislatively-referred constitutional amendment, where it was approved.[1] The measure permitted the legislature to reimburse municipalities for more than 50 percent of the property tax revenues loss caused by the enactment of statutory property tax exemptions or credits. It also permitted, but did not require, the legislature to reimburse municipalities for statutory property tax exemptions or credits for unextracted minerals. The measure also extended a penalty for a change in use of property to be determined without considering the presence of minerals in that property, so long as the mining of minerals would have been subject to a state excise tax at the time the determination of change of use was made. This amended Section 23 of Article IV, Part Third and Section 8 of Article IX of the Maine Constitution.[2][3]
